T0 on whom it may concern.-

Be it known that I, DANIELA. HARMON, a citizen of the United States,residing at Ingraham, in the countyof Clay andState of Illinois, haveinvented a new and useful WVell- Boring Machine, of which thefollowingis a specification.

My invention relates to machines for boring wells; and it consists inthe various features hereinafter described and more particularly claimedand as illustrated in the accompanying drawings, in which Figure 1 is aperspective view, Fig. 2, an enlarged vertical section of the base andoperating mechanism; Fig. 3, a plan view of the guide-clamp; Fig. 4, anelevation of the holding or gripping clamp.

' Similar characters indicate like parts throughout. the'several figuresof the drawings.

The letter F designates a base-frame, which may consist of a centralcylindrical member 10, provided with a vertical opening 11, throughwhich the auger and auger-shaft pass, and the lower and uppercylindrical reduced portions 11 and 11, respectively, and intersectingarms 12,forming a cross and each having successive lower and upper steps13 14, respectively. To these stepsare secured metal track-rings 15 16,which 'also serve as At opposite ends of the arms are secured the lowerends ofderrick members 17 17, connected at their upper ends by a rod 18,uponwhich is supported a pulley 19, and at their intermediatecrossbraces 20 by a cross-beam 23, just above the head ofa personstanding on the machine-platform.

Upon the lower track 15, about the portion 11 of the central member,operates a windlass-drum 24, preferably provided with separate rolls 25,journaled in its under side for side of the platform preferably lies inclose proximity to the upper face of the Windlass,

and the two elements may be compelled to rotate together'by a pin 33 orconnector extending through an opening 34 in the platform into a recess35 in the drum and be held into engagement with said recess by a spring36. The pin is preferably provided with a projection 37, operating in aslot 38 in the platform, so that when the pin is raised out of therecess and slightly turned about its axis it will lock it in thisposition and allow the Windlass to rotate independently of the platform.Radially from the platform extends a draft-bar 39, to which may beattached an animal to furnish power to the machine.

Above the platform at opposite sides of the are formed alined ways 4141.Oneach side of the ways of each standard are flanges 42, provided with avertical series of alined notches to receive at various heights afulcrum-bar 43. In the ways of the standards move rolls 44, turning uponthe ends 44 of a bar 45, having formed in it one jaw 46 of a clampmember 0, the movable jaw 47 being pivoted to the bar at 48 and beingshown as provided with a screw 49 for drawing it toward its companion topermit it to be clamped about the auger-shaft 50.

A second clamp O, the function of which will be hereinafter described,is also shown encircling the auger-shaft. As illustrated, this consistsof a pair of jaws 51 51, connected to each other by opposite pivot-bars52, about which they turn. A depression 53 may be formed in each jaw andbe faced with leather or other suitable material. A notched segment 54,pivoted to one member, extends through a slot and cooperating witha pin55 in the other allows the clamp to be maintained' fast upon the pipe.

Upon the Windlass is coiled the rope 70, which passes over a pulley 72,mounted upon the end of a brace 73, extending from the frame, andfinally up over the pulley 19.

Upon its depending end the rope carries a clamp O for raising thesections of the augershaft.

In the operation of the machine the anger is started through theopenings in the frame, Windlass, and platform, and the clamp-bar O issecured upon the auger-shaft to compel it auger-opening rise standards40 40, in which to rotate with the platform, while allowed to movethrough the same by the travel of the bar-rollers in the standard ways.Now if the pin 33 is raised to permit the independent movement of theplatform this may be rotated bya draft-animal, and, pressure beingapplied to the clamp 0 through a suitable lever coacting therewith andwith the fulcrum-bar, the augur will be advanced into the earth, thematerial removed rising through it. The clamp C is shifted upon theshaft whenever necessary. When a section of the shaft has gone down, theclamp O is loosened and the clamp 0 set upon it and by this is supportedupon the fulcrum-bar until a new section has been connected. This beingaccomplished, the clamp C is released and the clamp O restored, and theboring goes on as before. When it is desired to remove the shaft fromthe hole, the clamp C is lowered by its rope to the proper distance,preferably to a coupling, the yield of both jaws readily permittingthis, and the platform and Windlass being connected by the pin theWindlass is rotated by the draft-animal. The upward pullupon the clampthrows it into operative engagement with the pipe, causing it to be heldfirmly between the gripping members and causing the entire shaft to beraised. This continues until the coupling between the sections risesabove the platform. The lower .section is then caught and held by theclamp C while the coupling is disconnected, and the upper section isgrasped by one of a series of clamps S3 of any suitable form swingingupon the cross-beam 23. In a similar manner all the shaft-sections maybe withdrawn and held by the clamps 83, with their upper ends restingagainst the derrick, rendering it unnecessary to lower them to theground and leaving all convenient for immediate use. After the auger isdrawn from the well to empty the dirt it is again lowered into positionin the following manner: The rope and windlass allow the auger-box todescend until it has passed the fulcrum-bar, after which it is loweredwithout the assistance of either the rope or Windlass. The shaft iscaught by the clamp O at the fulcrum-bar and the clamp C" is removed ifit can be reached. If it is too high, the pin 33 is raised, which allowsthe Windlass to unwind and the clamp C to descend within reach, when itcan be released. The arms 51 of the clamp O are held by the hands,letting the shaft lowerat anyspeed desired to the proper distance. Whenpressure is exerted upon the arms, the shaft stops. The notched segment54 is then brought into engagement with the pin 55, and the clamp islocked in position, preventing further downward movement of the shaft.The next section is then coupled on, the segment released, and the shaftthen allowed to slide down through the clamping-arms, so that anothersection can be fastened on, if necessary.

It is to be understood that although I have described my preferred formof construction claimand arrangement of the several parts, yet I do notdesire to be limited to the exact arrangement or details ofconstructions, as numerous changes may be made without departing fromthe spirit of my invention.

= Having thus described my invention, I
